[2021] Why is the world so..... bumpy??

Grasslands are typically as flat is it gets, everything else will need to be terraformed. As admin you can take the fast route with the level command if so desired.

I play solo and must say that I was dissapointed on how bumpy the Small World size can get. So instead I started creating a Medium sized world that game suggests it sould be suitable for 3 cplayer Co-Op. Of course after generating world I then use Server UI that you can open using command /serverui to change the difficulty settings to No Nolaboration preset.
Generating large worl will make land even more suitable for building large bustling cities but does require a bit stronger computer to handle simulation at decent pace. Unfirtuately my now 10 year old computer is not powerfull for that so I stick to medium sized world instead.

Those settings are for 'difficulty', they don't change the world size as at all. For all single- and coop games we recommend default size, for public servers 1 km² instead of 0.52 km². For the biggest of public servers 2.56 km² is the absolute maximum we can recommend and any size above 4km² is unsupported, so usage at own risk.

The main issue is resource collection and using a cart... Cant seem to even get the cart up one tile high which means im spending most my time building ramps.
Terraforming is soooo tedious.
Moving one chunk of dirt at a time.
Not just digging it up but it also has to go somewhere as well.

Terraforming is something that should be done later with enough progress for heavy machinery. It's not a very basic or easy task to do.

Trucks, Cranes, Excavators and Skid Steers, yes.

Originally posted by SilverWarior: Wait was this changed then? I remember from past that if wen creating new game you would have chosen 0-3 Player coop and tick Generate world the game would generate a bit larger world than if you have done this by choosing Solo play.

No, it has never worked like this. The seting you mention is only for difficulty.
